Explaining the reason why validation is performed in to_str of path.rs I thought it's good to explain the reason for the validation during the conversion between Path/PathBuffer into str, which explains the reason for returning an Option at this point (good for beginners who are reading through the docs).

provide thread name to OS for Solarish systems Fixes #62302 Passes a Linux bootstrap build. python x.py test src/tools/tidy happy. I tested this with a small test binary that spawns a few threads, and verified that: - on an illumos system lacking the libc function, the binary runs but no OS-level thread names are set - on an illumos system with the feature, the binary runs, and the thread names are visible and correct under tools like MDB, pstack, core dump, etc.

simplify std::io::Write::write rustdoc The std::io::Write::write method currensly suggests consumers guaranteed that `0 <= n <= buf.len()`, for `Ok(n)`, however `n` is of type `usize` causing the compiler to emit a warning: ``` warning: comparison is useless due to type limits --> lib.rs:6:18 | 6 | Ok(n) => 0 <= n && n <= output.len(), | ^^^^^^ | = note: #[warn(unused_comparisons)] on by default ``` This PR removes the suggestion to check `0 <= n` since it is moot. r? @steveklabnik

Remove derives `Encodable`/`Decodable` and unstabilize attribute `#[bench]` `Encodable` and `Decodable` were deprecated before 1.0 and emitted an unsuppressable warning all this time. `#[bench]` is a part of the custom test framework feature and cannot be used meaningfully on stable, only as `cfg(false)`. Crater results can be found in https://github.com/rust-lang/rust/pull/62507#issuecomment-513850732 and below. This PR also reroutes the tracking issue for `feature(test)` from #27812 (compiler internals) to #50297 (custom test frameworks). Closes https://github.com/rust-lang/rust/issues/62048

std: Fix a failing `fs` test on Windows In testing 4-core machines on Azure the `realpath_works_tricky` test in the standard library is failing with "The directory name is invalid". In attempting to debug this test I was able to reproduce the failure locally on my machine, and after inspecing the test it I believe is exploiting Unix-specific behavior that seems to only sometimes work on Windows. Specifically the test basically executes: mkdir -p a/b mkdir -p a/d touch a/f ln -s a/b/c ../d/e ln -s a/d/e ../f and then asserts that `canonicalize("a/b/c")` and `canonicalize("a/d/e")` are equivalent to `a/f`. On Windows however the first symlink is a "directory symlink" and the second is a file symlink. In both cases, though, they're pointing to files. This means that for whatever reason locally and on the 4-core environment the call to `canonicalize` is failing. On Azure today it seems to be passing, and I'm not entirely sure why. I'm sort of presuming that there's some sort of internals going on here where there's some global Windows setting which makes symlinks behavior more unix-like and ignore the directory hint. In any case this should keep the test working and also fixes the test locally for me. It's also worth pointing out that this test was made Windows compatible in https://github.com/rust-lang/rust/pull/31360, a pretty ancient PR at this point.

rustc: Update wasm32 support for LLVM 9 This commit brings in a number of minor updates for rustc's support for the wasm target which has changed in the LLVM 9 update. Notable updates include: * The compiler now no longer manually inserts the `producers` section, instead relying on LLVM to do so. LLVM uses the `llvm.ident` metadata for the `processed-by` directive (which is now emitted on the wasm target in this PR) and it uses debuginfo to figure out what `language` to put in the `producers` section. * Threaded WebAssembly code now requires different flags to be passed with LLD. In LLD we now pass: * `--shared-memory` - required since objects are compiled with atomics. This also means that the generated memory will be marked as `shared`. * `--max-memory=1GB` - required with the `--shared-memory` argument since shared memories in WebAssembly must have a maximum size. The 1GB number is intended to be a conservative estimate for rustc, but it should be overridable with `-C link-arg` if necessary. * `--passive-segments` - this has become the default for multithreaded memory, but when compiling a threaded module all data segments need to be marked as passive to ensure they don't re-initialize memory for each thread. This will also cause LLD to emit a synthetic function to initialize memory which users will have to arrange to call. * The `__heap_base` and `__data_end` globals are explicitly exported since they're now hidden by default due to the `--export` flags we pass to LLD.

SystemTime docs: recommend Instant for elapsed time Introduction to `SystemTime` mentions problems with non-monotonic clocks, but individual methods don't. For benefit of users who jump directly to method's documentation, also recommend `Instant` in `elapsed` and `duration_since`. `SystemTime::elapsed()` docs overpromised the elapsed time. It's not elapsed time, but a difference between two clocks.

Move run-pass tests to ui This is the second attempt at doing https://github.com/rust-lang/rust/pull/53994 (which was previously reverted in https://github.com/rust-lang/rust/pull/54530). The issue with inability to run the test suite in a faster way (https://github.com/rust-lang/rust/issues/54047) that motivated the revert was recently addressed by https://github.com/rust-lang/rust/pull/61755. r? @Centril
